This comprehensive course provides a detailed understanding of IEC 60255-26 and IEC 60255-27, the internationally recognized standards for the EMC and product safety requirements of measuring relays and protection equipment. These standards are widely used by manufacturers, testing laboratories, certification bodies, utilities, and design engineers to ensure that protection relays operate safely, reliably, and without causing or being affected by electromagnetic disturbances.
Throughout this course, you will learn the complete requirements of IEC 60255-26, including electromagnetic compatibility (EMC) immunity tests, emission requirements, Electrostatic Discharge (ESD), Electrical Fast Transient (EFT), Surge immunity, Radiated and Conducted RF immunity, magnetic field immunity, voltage dips, interruptions, ripple tests, test levels, performance criteria, and laboratory test procedures.
You will also gain a thorough understanding of IEC 60255-27, which covers electrical safety requirements for measuring relays and protection equipment. The course explains protection against electric shock, insulation coordination, basic, supplementary, double and reinforced insulation, clearance and creepage distances, overvoltage categories, pollution degree, rated impulse voltage, dielectric withstand testing, impulse testing, insulation resistance, protective bonding, single-fault conditions, fire protection, mechanical safety, temperature limits, marking requirements, documentation, risk assessment, type testing, and routine testing.
